Audio just quit Macbook pro...

Up in the menu bar it shows full audio with adjustment but I have no audio. When I use the keyboard audio keys f3-f5 it shows a circle with a line through it. I went to the system prefs and it says "The Selected device has no output controls". I have restarted the system, removed the batter, quit everything... not sure what the problem is. This just happened out of no where. I have Mac Book Pro 10.4.8 2Ghz... This unit is only 5 months old.

Well i fixed the problem, I plugged in headphones and removed them right away and now it works. Note: if your audio is not working and for some reason there is a red light coming out of your headphones jack, just plug in headphones and remove them...

Thank you!

I had exactly the same problem and had tried all sorts of things (and searches) to solve it.

The headphone jack in then out solved it immediately.

Thank you so much for your posting!

No sound from internal speakers

Exact same thing happened to me. I have a Mac Book pro with Leopard 10.5. I was afraid that I had a major problem. For no reason that I could discern, all of a sudden I could not get sound from my internal speakers. All I had to do was insert a buddy's ear phones, pull them out right away and - presto - I'm back to normal.

Thank goodness for this forum, or I would have been in trouble.

I have a PowerBook G4 running Leopard 10.5.1, the same thing happened to me, but unfortunately the headphone jack in-out trick didn't work. Still searching for a solution ...

Worked for me too

The first few times I tried the headphone trick, it didn't work, but putting them in and pulling them out really quick did.

Thanks everybody!

I have seen this happen a lot on our Macbooks here at work. The earphone jack gets stuck in the "on" position which disables the speakers and routes all output to the head phone jack. In some cases it would be permanently stuck and I would have to get the main logic board replaced.

You can tell this is the case if you have no audio and then look at your head phone jack port on your laptop. If there is a red light inside of it, then it is stuck on and you will need to unstick it. I have heard of people using paper clips to flip the little switch in there, but that has never worked for me if it was broken. Sometimes by plugging in and then unplugging the head phones it worked, and sometimes it didn't.

Paperclip advice?

The "ol' head phone in and out trick" isn't working for me... any tips on what I should be poking at with the paper clip?

There's a microswitch inside the jack. A good flashlight should allow you to see it. If you use a paper clip, make sure that you don't wear down the edges of the microswitch, just change it's switch position. In fact, I'd advise a wooden toothpick over a paper clip, since the wood is softer and less likely to cause further problems.

If headphones don't work try this!

The headphone trick didn't work for me (macbook Pro)
The sensor on my Macbook Pro seems to be at the top of the port, I used a plastic tooth pick (with the sharp end removed), make sure it is as long as a headphone jack, bend the end up a little and with the bent part pointing up slide it in and them pull it out putting pressure to the top of the port.
Hope this helps!

No luck with Macbook Pro audio

I have not been able to solve this problem. It is a pre-2008 Aluminium Macbook Pro running Snow Leopard. I tried the audio plug idea. There is no red light. When it starts up there is a circle with a diagonal line through it. The volume control is gray. I can get sound with a USB or Firewire speaker. I can get sound in with a USB webcam. Any ideas?

I've had this problem as well. Tonight the fix was simple, though accidentally discovered: I rebooted single user for a completely unrelated reason with headphones jacked in. After I exited single user mode and the full boot commenced, once I logged in as me audio was back. So try restarting with headphones jacked in and report back. Not sure it's replicable, but I'm listening to Internet radio right now.

I've just had this problem with a MacBook Pro that's one month old. There wasn't a red light, and headphone in & out trick made no difference. I rebooted with the headphones plugged in, and that fixed it. Thanks Zonar!

Had this problem a coupla times over the years. Had it again just now 2008 MBP running Lion. Headphones wouldn't work this time, although previously that had been the solution, so I tried the paperclip thing and just gently rubbed it around the jack, and voila! the red light disappeared and I can hear again.

Thanks OS X Hints for being so awesome... and RIP Mr. Steve Jobs. I'll miss your inspiration.

Another solution

... After trying all methods on this forum, I came to a different resolution: For some reason my computer thought a bluetooth headset was present, although at the time I was only using a bluetooth mouse. Turning off the bluetooth in the system preferences altogether reset the audio output.

Hope this helps some people out of this frustrating problem.

Went to the "Genius" Bar earlier and their 'couldn't be bothered' solution was to replace the Logic Board for $500. Go figure!

An alternate way of fixing speakers

- I had the exact problem described by the original poster, redlight in headphone port, while headphones were working but speakers were coming up with a white no entry logo with no sound.

The above solution was not working for me but what did work was you have to put in the headphone jack with a bit of force and take it out again quickly with a bit of force (ofcourse not too much, but a bit forcibly).

You should now have your speakers working again.

After trying the headphone trick and reboot with headphones I found that it wasn't working.

- The way I made mine work is I put a bit of force into putting the headphone jack in, and quickly taking it out again (of course not too much force but enough so that the switch inside moves into place). Doing this a couple of times properly did the trick
